No, dry-type transformers are not filled with oil. Instead of using oil for cooling and insulation, they rely on air or other gases to dissipate heat. Their design eliminates the need for liquid insulation, making them safer and more environmentally friendly for certain applications.
Transformer oil is a specialized insulating oil used in power transformers to cool and insulate the internal components. It prevents electrical discharges, dissipates heat, and protects the transformer from moisture and oxidation. This ensures the efficient and reliable operation of the transformer, helping to extend its lifespan.
